Claims
I claim:
1. A method for making a casket lid having bevelled edge portions
and a generally domed configuration between the bevelled edges both
laterally and longitudinally of the lid, which method comprises
cutting a preformed corrugated board to form a generally
rectangular blank of overall dimensions approximating the length
and width of the lid, said board comprising preformed corrugated
fiberboard incorporating at least one corrugated sheet between at
least two uncorrugated sheets, forming generally diagonal cut-outs
in the corners of said blank to partially separate the end sections
of the blank from the central section thereof, scoring the cut
blank on a multiplicity of lines extended longitudinally of the lid
in the area between the portions to be incorporated in the bevelled
side edges and extended lengthwise of the blank between said
cut-outs, further scoring the cut blank along lines parallel to the
length of the lid in positions to accommodate the formation of the
bevelled side edges, scoring the end sections of the blank along
lines transverse to the length of the lid in position to
accommodate the formation of the bevelled end edges, flexing the
edge portions of the blank to form the bevelled edges around the
margin of the lid, flexing the central section of the blank on said
score lines between the bevelled edge portions to provide
progressive increase in the height of the lid in a multiplicity of
stages as the central region is approached and thereby provide the
laterally domed configuration of the lid, flexing the end sections
of the blank to provide for closure of the diagonal cut-outs in the
corners of the blank, securing transverse bridge members to the
lid, at least one of which is secured to the lid in the mid-region
of the laterally domed contour portion thereof, and one of which is
secured to the lid toward each end of the lid in the region of the
longitudinally domed end portions thereof, and securing framing
elements to at least some edges of the lid.
2. A method as defined in claim 1 in which the flexing of the end
sections of the lid between the diagonal cut-outs is effected to
provide the bevelled end edges of the lid and to provide an upward
but reduced inclination of the end section areas inboard of the
bevelled end edges.
3. A method for making a casket lid having bevelled edge portions
at both the side and end edges of the lid and a domed configuration
between the bevelled edges both laterally and longitudinally of the
lid, which method comprises cutting a preformed corrugated board to
form a generally rectangular blank of overall dimensions
approximating the length and width of the lid, said board
comprising preformed corrugated fiberboard incorporating at least
one corrugated sheet between at least two uncorrugated sheets,
forming generally diagonal cut-outs in the corners of said blank to
partially separate the end sections of the blank from the central
section thereof in the region forming both the bevelled edges and
domed portions of the lid, scoring the cut blank along lines
extended longitudinally of the lid in positions to accommodate the
formation of the bevelled side edges, scoring the end sections of
the blank along lines transverse to the length of the lid in
position to accommodate the formation of the bevelled end edges,
flexing the edge portions of the blank along said scoring lines to
form the bevelled edge around the margin of the lid, flexing the
centnral section of the blank in the region between said bevelled
edges to provide progressive increase in the height of the lid in
the region between said bevelled edges as the central region is
approached and thereby provide the laterally domed configuration of
the lid between said bevelled edges, flexing the end sections of
the blank to provide for closure of the diagonal cut-outs in the
corners of the blank, and securing framing elements to at least
some edges of the lid.
4. A method as defined in claim 3 in which the flexing of the end
sections of the lid between the diagonal cut-outs is effected to
provide the bevelled end edges of the lid and to provide an upward
but reduced inclination of the end section areas inboard of the
bevelled end edges.
5. A method for making a casket lid having bevelled edge portions
at both the side and end edges of the lid and a domed configuration
between the bevelled edges both laterally and longitudinally of the
lid, which method comprises:
(a) preparing a generally rectangular blank, the blank being formed
of preformed corrugated fiberboard incorporating at least one
corrugated sheet between at least two uncorrugated sheets, the
preparation of the blank including:
(a1) cutting the blank with overall dimensions approximating the
length and width of the lid and with generally diagonal cut-outs in
the corners of said blank to partially separate the end sections of
the blank from the central section thereof in regions providing for
forming both lateral and longitudinal bevelled edges and for
forming a central region which is domed both laterally and
longitudinally; and
(a2) scoring the corrugated fiberboard along lines extended
longitudinally of the lid in positions to accommodate the formation
of the bevelled side edges and along lines transverse to the length
of the lid in positions to accommodate the formation of the
bevelled end edges;
(b) flexing the side and end edge portions of the blank along said
scoring lines to form the bevelled edges around the margin of the
lid and to form the central section of the blank in the region
within said bevelled edges to provide progressive increase in the
height of the lid in the region within said bevelled edges as the
central region is approached both laterally and longitudinally of
the lid and thereby provide both the lateral and the longitudinal
domed configuration of the lid within said bevelled edges, said
flexing further providing for closure of the diagonal cutouts in
the corners of the blank and for bringing together said bevelled
side and end edges around the perimeter of the lid and also
bringing together the laterally and longitudinally domed portions
of the lid; and

Description
BACKGROUND AND STATEMENT OF OBJECTS
This invention relates to caskets or coffins and is particularly
concerned with a casket lid formed, at least in part, of corrugated
fiberboard sheet material.
The fabrication of caskets and casket lids from corrugated
fiberboard is known, but some problems have been encountered in the
fabrication of casket lids of domed configuration.
The primary objective of the present invention is to provide a
novel technique for the fabrication of a casket lid from corrugated
fiberboard, and the invention is particularly concerned with the
fabrication of a casket lid which has the domed configuration not
only laterally of the lid but also longitudinally thereof.
It is an object of the invention to provide for such fabrication of
a domed casket lid from corrugated fiberboard provides a lid
structure of substantial strength and igidity, notwithstanding the
formation of the lid from corrugated fiberboard.
It is also an object of the invention to provide for the
fabrication of a corrugated fiberboard casket lid in a
configuration in which transverse bridges or strengthening members
are applied to the lid in a manner providing for use of the lid
either in a single piece or alternatively as a split lid, i.e., in
two pieces. This is accomplished by cutting the originally formed
complete lid structure in the central region between transverse
strengthening bridge members, thereby providing lid sections, each
of which has adequate rigidity and strength.

DETAILED DESCRIPTION OF THE DRAWINGS
In considering various figures of the drawings, it should be kept
in mind that the lid of the present invention is suitable for use
with a wide variety of casket shells. In a typical case, it is
contemplated that the casket lid of the invention will be applied
to a casket shell similarly formed of corrugated fiberboard. The
shell shown in FIGS. 1, 3, 4, 13 and 14 has an upwardly flared
configuration between the side walls 15 and also between the end
walls 16. In a typical case, the shell is provided with a wood
frame at its upper edge, as indicated at 17, the frame 17.
Appropriate handles or other hardware may also be provided on the
shell, such as indicated at 18, in any desired manner.
Although it is contemplated that the lid of the present invention
be used with a shell which is similarly formed of corrugated
fiberboard sheet material, the figures of the drawings do not
illustrate the details of the corrugated fiberboard shell, since
that structure forms no part of the present invention per se.
From FIGS. 1, 2, 3 and 4, it will be seen that the lid is of domed
configuration both longitudinally and transversely of the lid and
of the casket. The central portion 19 of the lid is transversely
domed and the end portions 20 are longitudinally domed. Preferably
also, the central and end domed portions of the lid are surrounded
by a beveled edge part indicated at 21, this beveled edge part
being extended all the way around the lid, as will be clear from
examination of FIGS. 1 to 4. In FIGS. 1 to 4, the corrugated
character of the fiberboard is not illustrated; but from other
figures described hereinafter, it will be understood that the main
sheet elements of the lid are formed of corrugated fiberboard.
In the fabrication of a lid according to this invention, a blank is
cut from corrugated fiberboard sheet material, preferably multiple
corrugated fiberboard, for instance, fiberboard having two
corrugated layers, as indicated at 22 in FIG. 9, these layers being
assembled with three planar sheets indicated at 23. As will be
noted from FIG. 9, the corrugations run transversely of the length
of the lid. As seen in FIG. 5, the corrugated sheet material is cut
to form a blank of overall general dimensions corresponding to the
length and the width of the casket lid being formed. The blank has
a central section or area generally indicated at 24 corresponding
to the principal portion of the central region of the casket lid;
and the blank also includes end portions or sections 25
corresponding to the end portions of the lid. These various areas
are defined in part by the cutting of generally diagonal cut-outs
indicated a 26.
The central area 24 is then provided with score lines indicated at
27 (see also FIG. 9a). These score lines facilitate and provide for
uniformity of flexure of the blank in the central region in order
to provide the transversely domed configuration of the lid. The
marginal score lines at the opposite sides of the central region
also provide for folding of the edges of the lid around the side
frame members 28 (see particularly FIGS. 3 and 10). The score lines
also aid in defining the edges of the beveled edge areas 21.
The end areas 25 of the blank are also provided with certain score
lines 29, as will be seen in FIG. 5, and those score lines
similarly aid in defining the beveled edges in the end portions of
the lid and also provide for folding of the edges around the frame
elements 30 (see FIGS. 4 and 10). Preferably, the frame elements 28
and 30 are formed of wood, and as seen in FIGS. 3 and 4, the
terminal edge portions of the blank may be fastened to the frame
elements 28 and 30 as by stapling indicated at 31.
Transverse marginal bridges are also applied inside of the lid,
these bridges being indicated at 32 in FIGS. 2, 3, 4, 10, 13 and
14. These bridges are also preferably formed of corrugated
fiberboard and may comprise material similar to that illustrated in
FIG. 9, but preferably, the bridges comprise a greater number of
layers of the corrugated and planar sheets, for instance, four
corrugated layers, with intervening planar sheets. If desired, the
bridges may be formed by laminating two corrugated sheets of the
kind shown in FIG. 9 to each other and then cutting the bridges
from that laminated assembly. By this use of multiple-layered
corrugated material, the bridges will provide a very high degree of
strength and rigidity.
The edges of the blank are desirably notched, as indicated at 32a,
to accommodate the bridges when the edges of the blank are folded
around the frame elements 28.
It will further be observed that in the embodiment illustrated, a
bridge 32 is positioned adjacent to the junction between each end
section of the lid and the central section thereof, and in addition
to these two end bridges, a pair of bridges 32 are located in the
central region of the central area of the lid, as clearly appears
in FIG. 2. Slight spacing between these two central bridges along
the line indicated at x--x in FIG. 2 provides freedom for cutting
the formed lid into two sections, so that the lid may alternatively
be used in sectionalized form, instead of as a single unit. Such a
sectionalized portion of the lid is shown in FIGS. 13 and 14.
As above indicated, in addition to the transversely domed
configuration of the central portion of the lid, the end portions
may also be curved to domed shape, the cutouts 26 being configured
and positioned so as to accommodate this longitudinal domed
configuration and provide a meeting line joining the edge portions
of the central region. When the central region and the end portions
are flexed to the domed configuration desired, fiberboard "patches"
33 may be adhesively applied to the inside surface of the lid being
formed in order to unify the structure of the central section and
the end sections.
To further reinforce and strengthen the lid, liner inserts, such as
shown in FIGS. 11 and 12, are preferably applied to the lid between
the bridges 32. These liner inserts comprise rectangular portions
indicated at 34 in FIG. 11 adapted to be flexed and adhesively
applied to the central sections at each side of the central bridges
32.
Material appropriate for use as liner inserts is indicated in the
enlarged fragmentary sectional view of FIG. 12. Thus, it will be
seen that a single corrugated layer 36 and a single flat sheet 37
are preferably employed, the planar sheet 37 being presented
inwardly and the corrugated layer being adhesively applied to the
under surface of the lid. The corrugations of the corrugated layer
36 of the inserts 34 desirably extend lengthwise of the lid in
order to avoid wrinkling when the inserts are flexed to fit the
contour of the lid.
It will be understood that appropriate hinges and latches may be
appled in order to connect the frame of the casket lid to the frame
of the casket shell.
It is also contemplated that the interior of both the shell and the
lid may be covered with appropriate fabric, and in the arrangement
of the lid, such fabric strips may readily be applied over the
entire inner surface of the lid, covering not only the main central
and end areas but also covering the transverse bridges. A portion
of such a fabric covering is indicated fragmentarily at 35 in FIG.
14.
According to the foregoing, a casket lid is provided having domed
configuration not only transversely but also longitudinally, and
this is accomplished in a relatively simple manner from relatively
inexpensive materials, while at the same time, providing
substantial rigidity and strength.
